Geomorphology of Ponta Grossa’s Grid, State of Paraná – An Emphasis to the Geotechnological Resources Used

Abstract

Through the use of different possibilities of softwares, this paper proposes an geomorphological mapping, aiming to define geomorphological compartments for an area measuring around 12,000 Km², who covers the Ponta Grossa's Grid. Different techniques, programs and methodology treated at geotechnologies, has favored papers with geomorphological focus, according as, this provide faster and effectiveness, the identification of textures, forms, and form patterns, verified at remote sensing products, like orbital and radar images, and aerial photography. This analysis tools are actually utilized, when attempting to characterize domains or geomorphological compartments and even, surface's processes. The geomorphological compartments of Ponta Grossa's Grid was obtained, involving data like lithological (Mineropar, 2001), morphometric of relief (slope, hypsometric), and those supplied by drainage and structural lineaments chart. Therefore, were indentified nine geomorphological compartments: CG1 - Serrinha High Plateau (PAS); CG2 - Steep Middle Plateau (PMe); CG3 - Low Plateau reworked by Iguaçu river (PBrI); CG4 - Flat top Middle Plateau (PMtp); CG5 - Middle Plateau reworked by Iguaçu River (PMrI); CG6 - Strongly dissected Middle Plateau (PMfd); CG7 - Dissected High Plateau (Pad); CG8 - Intensely Fractured Low Plateau (PBif) e CG9 - Fractured and reworked Low Plateau (PBfr).
